SAFETY GAGE-COCK.

Specification of Letters Patent.

Patented Jan. 26, 1915.

Application filed May 20, 1914. Serial No. 839,813.

To all "whom it may concern Be it known that I, EDWARD BELLINGER, acitizen of the United States, residing at Rocky Ford, in the county ofOtero and State of Colorado, have invented new and useful Improvementsin Safety Gage- Cocks, of which the following is a specification.

This invention relates to safety gage cocks, the object of the inventionbeing to provide a gage cock which will automatically cut off thepressure in case the gage glass breaks.

A further object of the invention is to provide in connection with agage cock of the class referred to, a hand controlled valve by means ofwhich the pressure may be cut off independently of the automatic checkvalve and by means of which also said automatic check valve may bedisplaced so as to open up communication with the gage glass for blowingthe latter out.

With the above and other objects in view,

the invention consists in the novel construc-.

tion, combination and arrangement of parts, as will be hereinafter morefully described, illustrated and claimed.

The accompanying drawing represents partly in elevation and partly inlongitudinal section a safety gage cock embodying the present invention.

Referring to the drawings A designates the body of the gage cock, thesame being provided with a valve chamber 1 extending longitudinally ofone end of the body, and a pressure inlet passage 2 extendinglongitudinally of the other end of the body. The valve chamber 1 and thepressure inlet passage 2- are connected by means of an inter mediatepassage 3 which extends obliquely in relation to the chamber 1 andpassage 2 and in which is arranged an automatic check valve 4: shown inthe form of a ball. The passage 3 extends on both sides of the adjacentend of the passage 2 and the outer'end portion of the intermediatepassage 3 is internally threaded to receive the threaded shank 5 of anadjustable valve support 6 against which the valve 4 is adapted to restwhen out of its working position. The valve support 6 is provided at itsouter end with a head 7 to provide for adjusting the same. At its innerend the intermediate passage 3 communicates with the inner end of thevalve chamber 1 by means of a small opening 8 which terminates at itsopposite ends in valve seats 9 and 10, the last named seat beingprovided for the automatic check valve 4.

The seat 9 is provided for a cone-shaped valve 11 on the inner end of avalve stem 12 which is threaded at 13 through the end of the valve body1, the stem also passing through a stufiing box or gland 14 and beingprovided at its outer end with a handle or wheel 15 by means of which itmay be turned. The valve 11 is provided with a displacement pin 16extending from its smaller end and adapted to pass through the opening 8and come in contact with the automatic check valve 1 for the purpose ofdisplacing the latter from its seat and thereby allowing the pressure toflow through the passages 2 and 3 and into the valve chamber 1 which isalways in open communication with the gage glass shown at 17, the latterbeing fitted to the body A by means of a gland 18. In case the gageglass should break, the automatic check valve 1 will be immediatelyseated by means of the pressure behind it and will thereby instantly out01f communication with the valve chamber 1. The operator may then screwthe valve 11 tightly against its seat 9 until a repair has been made.

Two of the gage cocks are shown in the drawing, one. at the top and theother at the bottom of the gage glass 17. Both of the gage cocks are thesame in construction and operation as hereinabove described and shown inthe upper sectional part of the drawing.

What I claim is 1. In a safety gage cock, a body formed with a pressureinlet passage extending longitudinally of one end of said body, a valvechamber extending longitudinally of the other end of said body and inopen communication with the gage glass, and an intermediate passageconnecting said longitudinal passages and extending obliquely inrelation thereto, a pressure seated check valve movable longitudinallyof said intermediate passage and adapted to cut off communicationbetween said intermediate pas sage and said valve chamber, and a handoperated valve in said valve chamber adapted to cut oil communicationbetween said chamber and intermediate passage and provided with adisplacement pin adapted to extend into said intermediate passage andunseat said check valve.

other end of said body and in open communication with the gage glass,and an intermediate passage connecting said l0ngitudinal passages andextending obliquely in relation thereto, a pressure seated check valvemovable longitudinally of said intermediate passage and adapted to cutoff communication between said intermediate passage and said valvechamber, a hand operated valve in said valve chamber adapted 60191:: ofthis pate-n11 may be obtained for five cents each, by addressing theCommissioner of Washington, I). O.

to out ofi' communication between said chamber and intermediate passageand provi ded with a displacement pin adapted to extend into saidintermediate passage and unseat said check valve, and an adjustablesupport for said check valve When in nonchecking position.

In testimony whereof I afIiX my signature in presence of two witnesses.V
